Abstract: A method performed by a terminal in a wireless communication system according to an embodiment of the present disclosure comprises the steps of: receiving a group-common transmission regarding a TB from a network; transmitting hybrid automatic repeat request (HARQ) acknowledgement (ACK) or non-acknowledgement (NACK) information regarding the group-common transmission to the network, on the basis of whether the TB is successfully decoded; and receiving first transmission from the network after a first round trip time (RTT) has lapsed since transmission of the HARQ ACK/NACK information regarding the group-common transmission. The first transmission corresponds to group-common transmission or terminal-specific transmission. The first transmission may correspond to retransmission of the TB on the basis that the first transmission is terminal-specific transmission associated with the same HARQ process as the group-common transmission, and that a new data indicator (NDI) value is not toggled.

Abstract: Disclosed is a method for transmitting and receiving signals to enable a terminal to perform a random access channel procedure (RACH procedure) in an unlicensed band. In particular, the method comprises: transmitting an uplink signal including a first physical random access channel (PRACH) and a first physical uplink shared channel (PUSCH) to a base station; and receiving, from the base station, a downlink signal related to contention resolution in response to the uplink signal, wherein a power ramping counter is used to set the transmission power of the uplink signal, and the value of the power ramping counter may be increased on the basis of a transmission spatial beam for the transmission of the uplink signal being configured in the same manner as a transmission spatial beam for the transmission of a PRACH prior to the uplink signal.

Abstract: A method and apparatus for handling signaling delay for handover is provided. A wireless device transmits a measurement report based on a first event for a first cell, receives a handover command which commands a handover to the first cell, and checks validity of the handover command based on the first event for the first cell and/or a second event for a second cell other than the first cell.

Abstract: Provided are a method for a user equipment (UE) to perform early data transmission (EDT) in a wireless communication, and an apparatus supporting the same. The method may include: transmitting a first radio resource control (RRC) message for the EDT, to a base station; receiving a second RRC message in response to the first RRC message, from the base station; if the second RRC message indicates that the EDT is successful, considering that the EDT ends successfully; if the second RRC message indicates that the EDT is unsuccessful, considering that the EDT ends unsuccessfully; and entering a RRC_IDLE state.

Abstract: Provided are a method for requesting, by a user equipment (UE), system information in a wireless communication system and a device supporting the same. The method may include: initiating a random access procedure; requesting system information from a base station (BS) in the initiated random access procedure; receiving, from the BS, a broadcast indication indicating that the requested system information is broadcast in the initiated random access procedure after requesting the system information from the BS; and stopping the initiated random access procedure.

Abstract: Provided are a method and a device for receiving information indicating the type of a signaling radio bearer (SRB) in a wireless communication system. A user equipment (UE): receives a first radio resource control (RRC) message including information indicating the type of SRB on which a second RRC message, which is a message corresponding to the first RRC message, is to be transmitted; and transmits the second RRC message via the type of SRB indicated by the information indicating the type of SRB. Accordingly, the type of bearer on which a first message is received and the type of bearer on which a second message is transmitted in a single RRC procedure may be identical or mutually different.

Abstract: The present disclosure relates to transmission prioritization in wireless communications. According to an embodiment of the present disclosure, a method performed by a wireless device in a wireless communication system comprises: configuring a threshold; creating a media access control (MAC) protocol data unit (MAC PDU) for sidelink comprising a MAC control element (CE); setting a priority value to the MAC CE; identifying a transmission of the MAC PDU for sidelink and an uplink transmission to be performed; determining that the transmission of the MAC PDU for sidelink and the uplink transmission are not able to be performed simultaneously; determining that the priority value of the MAC CE is lower than the threshold; prioritizing the transmission of the MAC PDU for sidelink over the uplink transmission; and performing the transmission of the MAC PDU for sidelink that is prioritized over the UL transmission.
